Copper Alloy C19500-O60 vs C19500-TF00

Copper Alloy · C19500 temper comparison

C19500-O60 and C19500-TF00 are two conditions of the same copper alloy grade, C19500: O60 (soft annealed) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C19500-TF00 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 170 MPa (24.7 ksi) for C19500-O60, about 176% more; tensile strength follows at 540 MPa (78.3 ksi) vs 400 MPa (58 ksi). In exchange, C19500-O60 is the more ductile: elongation 24% versus 10% for C19500-TF00, and C19500-TF00 is harder (160 HV vs 100 HV). C19500-TF00 conducts heat better (215 W/m·K vs 185 W/m·K).

C19500-O60 vs C19500-TF00 — frequently asked

Is C19500-TF00 stronger than C19500-O60?

Yes. C19500-TF00 has a typical yield strength of 470 MPa (68.2 ksi) against 170 MPa (24.7 ksi) for C19500-O60 — about 176% more. Tensile strength is 540 MPa (78.3 ksi) vs 400 MPa (58 ksi).

Which condition does FabDigit quote by default, O60 or TF00?

H02 is the default C19500 condition in the FabDigit quote flow (neither O60 nor TF00). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, C19500-O60 or C19500-TF00?

C19500-TF00, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for C19500-O60.
